Answer:
True
Explanation:
A car is designed to utilize fuel as its source of energy. This fuel contains chemicals, which the engine of the car breaks down via combustion to facilitate its functioning. Kinetic energy is a form of mechanical energy produced as a result of motion. A moving object, individual etc uses kinetic energy to do so.
The fuel (gasoline) being supplied into the car's engine makes the car able to move, hence, we can say that the chemical energy present in the fuel is being converted to kinetic energy (observable in the car on motion) with the release of heat by the engine.
Until recently, prokaryotes did not contain linear plasmids or chromosomes, but they have since been discovered in spirochaetes, Gram-positive bacteria, and Gram-negative bacteria. Bacterial linear DNA has been classified into two structural kinds. Each end of linear plasmids from the spirochaete Borrelia has a covalently closed hairpin loop, while each end of linear plasmids from the Gram-positive filamentous Streptomyces has a covalently connected protein. In eukaryotic cells, replicons with comparable structures are more common than in prokaryotes. However, linear genomic architectures are likely more widespread in bacteria than previously thought, and some replicons may be able to switch between circular and linear isomers. The molecular biology of these widely scattered pieces reveals information about the origins of linear DNA in bacteria, including evidence of prokaryote-eukaryotes genetic exchange.
Answer:
1) pathway taken by water
water is absorbed from the soil, through the root hair cells and is transported by the xylem vessel up the stem to the leaf and/or flowers. From the leaf, some water is lost to the atmosphere as vapors escape out through the stoma present in the lower epidermal layer of the leaves.
2) water potential gradient
water potential refers to the concentration of water present. A gradient forms when there is a difference between the concentrations of water in two regions separated by a partially permeable membrane.
Hence, water moving down a water potential gradient means that it goes from a region of high water potential to a region of low water potential.
3) There are tiny openings on the lower side of the leaves called as stomata (plural: stoma) that allow for gaseous exchange to occur. These openings are controlled by guard cells which are open during the day and close during the night.
Hope that answers the question, have a great day!
